14 Then Joab said, "I cannot linger with you." And he took three spears in his hand and thrust them through Absalom's heart, while he was still alive in the midst of the terebinth tree. 15 And ten young men who bore Joab's armor surrounded Absalom, and struck and killed him. 16 So Joab blew the trumpet, and the people returned from pursuing Israel. For Joab held back the people. 17 And they took Absalom and cast him into a large pit in the woods, and laid a very large heap of stones over him. Then all Israel fled, everyone to his tent. 18 Now Absalom in his lifetime had taken and set up a pillar for himself, which is in the King's Valley. For he said, "I have no son to keep my name in remembrance." He called the pillar after his own name. And to this day it is called Absalom's Monument.
19 Then Ahimaaz the son of Zadok said, "Let me run now and take the news to the king, how the Lord has avenged him of his enemies." 20 And Joab said to him, "You shall not take the news this day, for you shall take the news another day. But today you shall take no news, because the king's son is dead." 21 Then Joab said to the Cushite, "Go, tell the king what you have seen." So the Cushite bowed himself to Joab and ran. 22 And Ahimaaz the son of Zadok said again to Joab, "But whatever happens, please let me also run after the Cushite." So Joab said, "Why will you run, my son, since you have no news ready?" 23 "But whatever happens," he said, "let me run." So he said to him, "Run." Then Ahimaaz ran by way of the plain, and outran the Cushite. 24 Now David was sitting between the two gates. And the watchman went up to the roof over the gate, to the wall, lifted his eyes and looked, and there was a man, running alone. 25 Then the watchman cried out and told the king. And the king said, "If he is alone, there is news in his mouth." And he came rapidly and drew near. 26 Then the watchman saw another man running, and the watchman called to the gatekeeper and said, "There is another man, running alone!" And the king said, "He also brings news." 27 So the watchman said, "I think the running of the first is like the running of Ahimaaz the son of Zadok." And the king said, "He is a good man, and comes with good news." 28 And Ahimaaz called out and said to the king, "All is well!" Then he bowed down with his face to the earth before the king, and said, "Blessed be the Lord your God, who has delivered up the men who raised their hand against my lord the king!" 29 The king said, "Is the young man Absalom safe?" Ahimaaz answered, "When Joab sent the king's servant and me your servant, I saw a great tumult, but I did not know what it was about." 30 And the king said, "Turn aside and stand here." So he turned aside and stood still. 31 Just then the Cushite came, and the Cushite said, "There is good news, my lord the king! For the Lord has avenged you this day of all those who rose against you." 32 And the king said to the Cushite, "Is the young man Absalom safe?" So the Cushite answered, "May the enemies of my lord the king, and all who rise against you to do harm, be like that young man!"

Commentary on 2 Samuel 18:9-18
(Read 2 Samuel 18:9-18)
Let young people look upon Absalom, hanging on a tree, accursed, forsaken of heaven and earth; there let them read the Lord's abhorrence of rebellion against parents. Nothing can preserve men from misery and contempt, but heavenly wisdom and the grace of God.
Commentary on 2 Samuel 18:19-33
(Read 2 Samuel 18:19-33)
By directing David to give God thanks for his victory, Ahimaaz prepared him for the news of his son's death. The more our hearts are fixed and enlarged, in thanksgiving to God for our mercies, the better disposed we shall be to bear with patience the afflictions mixed with them. Some think David's wish arose from concern about Absalom's everlasting state; but he rather seems to have spoken without due thought. He is to be blamed for showing so great fondness for a graceless son. Also for quarrelling with Divine justice. And for opposing the justice of the nation, which, as king, he had to administer, and which ought to be preferred before natural affection. The best men are not always in a good frame; we are apt to over-grieve for what we over-loved. But while we learn from this example to watch and pray against sinful indulgence, or neglect of our children, may we not, in David, perceive a shadow of the Saviour's love, who wept over, prayed for, and even suffered death for mankind, though vile rebels and enemies.
